What is Assured Positioning, Navigation and Timing?
The potential vulnerabilities of the military’s dependence on Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) data are driving demand for new deployed approaches for detecting threats. In GPS/GNSS-denied environments, ensuring accurate Positioning, Navigation and Timing (PNT) information is delivered to the warfighter is absolutely critical.
Simplifying integration & ensuring user confidence
Designing and developing an A-PNT solution that seamlessly integrates information from multiple complementary sources and provides the same level of performance as GPS is not an easy task. From a design and engineering perspective, there are – quite literally – a lot of moving parts to consider and combine to arrive at a PNT truth. This white paper explores the challenges involved in developing effective and reliable A-PNT solutions, and provides guidelines for taking a holistic approach to A-PNT for maximum effectiveness.
